The GRIP FORCE GEN 123 ADAPTER was developed specifically for GLOCK's GEN 1, GEN 2, and GEN 3 series of pistols.

It eliminates the drawbacks associated with permanent modifications to your factory pistol. The GRIP FORCE GEN 123 ADAPTER mates completely to the back strap of the GLOCK frame, permitting the shooter's hand to conform to the frame in a more secure manner. This offers more control and allows the shooter to index the pistol on target more efficiently.

*In 2007 and later, GLOCK produced some pistols (in 9mm and .40 caliber), that have
slightly thicker frames than most other GEN 3 pistols. These frames, which have a
serial number prefix starting with the letter L (i.e. LXX123), are oversized in diameter at the trigger housing pin location.The GEN 123 GRIP ADAPTER may not fit on these
oversized frames. This is a very small number of frames, and the majority of L Series serial numbered frames have no fit problems whatsoever.

*The GEN 123 ADAPTER will also work on a GEN 4 Pistol if the GLOCK factory Medium grip panel is installed on the GEN 4 frame.

The horizontal ridges on the underside of the GEN 123 ADAPTER may need to be slightly reduced in order for
it to fit over top of the factory Medium grip panel.
